# What this is: Deployment test for the Tacker Hello World blueprint.
#
# Status: work in progress, planned for OPNFV Danube release.
#
# Use Case Description: A single-node simple python web server, connected to
# two internal networks (private and admin), and accessible via a floating IP.
# Based upon the OpenStack Tacker project's "tosca-vnfd-hello-world" blueprint,
# as extended for testing of more Tacker-supported features as of OpenStack 
# Newton.
#
# Pre-State: 
# This test can be run in either an OPNFV environment, or an plain OpenStack
# environment (e.g. Devstack). 
# For Devstack running in a VM on the host, you must first enable the host to 
#   access the VMs running under Devstack:
#   1) In devstack VM: 
#      $ sudo iptables -t nat -A POSTROUTING -o ens3 -j MASQUERADE
#      Sub the primary interface of your devstack VM for ens3, as needed.
#   2) On the host (e.g linux): 
#      $ sudo route add -net 172.24.0.0/16 gw 192.168.122.112
#      Sub your devstack Public network subnet for 172.24.0.0/16, and 
#      your devstack VM IP address on the host for 192.168.122.112
# For OPNFV-based tests, pre-requisites are
#   1) models-joid-001 | models-apex-001 (installation of OPNFV system)
#
# Test Steps and Assertions:
# 1) bash vHello_Tacker.sh setup <openrc> [branch]
#   models-tacker-001 (Tacker installation in a docker container on the jumphost)
#   models-nova-001 (Keypair creation)
# 2) bash vHello_Tacker.sh start
#   models-tacker-002 (VNFD creation)
#   models-tacker-003 (VNF creation)
#   models-tacker-vnfd-001 (config_drive creation)
#   models-tacker-vnfd-002 (artifacts creation)
#   models-tacker-vnfd-003 (user_data creation)
#   models-vhello-001 (vHello VNF creation)
# 3) bash vHello_Tacker.sh stop
#   models-tacker-004 (VNF deletion)
#   models-tacker-005 (VNFD deletion)
#   models-tacker-vnfd-004 (artifacts deletion)
# 4) bash vHello_Tacker.sh clean
#   TODO: add assertions
#
# Post-State: 
# After step 1, Tacker is installed and active in a docker container, and the 
# test blueprint etc are prepared in a shared virtual folder /tmp/tacker.
# After step 2, the VNF is running and verified.
# After step 3, the VNF is deleted and the system returned to step 1 post-state.
# After step 4, the system returned to test pre-state.
#
# Cleanup: bash vHello_Tacker.sh clean
#
# How to use:
#   $ git clone https://gerrit.opnfv.org/gerrit/models
#   $ cd models/tests
#   $ bash vHello_Tacker.sh [setup|run] [<openrc>] [<heat_host>] [branch]
#     setup: setup test environment
#     <openrc>: location of OpenStack openrc file
#     <heat_host>: IP address of the Heat service
#     branch: OpenStack branch to install (default: master)
#   $ bash vHello_Tacker.sh [start|stop|clean]
#     run: setup test environment and run test
#     start: install blueprint and run test
#     stop: stop test and uninstall blueprint
#     clean: cleanup after test
